A receiver for a light transmission system includes a camera having an image sensor, and a light-sensitive area of the image sensor includes a plurality of rows of light-sensitive elements. The image sensor is configured such that the light-sensitive area of the image sensor is scanned row by row or column by column. An attachment element is arranged such that light incident on the light-sensitive area of the image sensor passes through the attachment element beforehand. The attachment element has at least one lenticular region and at least one planar region.
Legal claims defining the scope of protection, as filed with the USPTO.
2. The receiver according to claim 1, wherein the attachment element is foil- or plate-shaped, the lenticular region has an alternating material thickness, and the planar region has a constant material thickness.
3. The receiver according to claim 1, wherein a material thickness of the lenticular region is constant in a preferred direction and is alternating in a transverse direction perpendicular to the preferred direction.
4. The receiver according to claim 1, wherein the attachment element includes a plurality of stripe-shaped lenticular regions and a plurality of stripe-shaped planar regions.
5. The receiver according to claim 4, wherein the stripe-shaped lenticular regions are oriented parallel to a transverse direction.
6. The receiver according to claim 1, further comprising an accommodating unit, including a first accommodating element and a second accommodating element movable relative to the first accommodating element, the camera being accommodated in the first accommodating element, and the attachment element being accommodated in the second accommodating element.
7. The receiver according to claim 1, wherein the lenticular region includes a plurality of bumps arranged side by side in a transverse direction.
8. The receiver according to claim 7, wherein the bumps are semicircular-shaped.
9. The receiver according to claim 1, wherein the lenticular region and the planar region are arranged adjacent to each other on a same side of the attachment element.
10. The receiver according to claim 1, wherein light that passes through the planar region is not diffracted by the attachment element.
12. The system according to claim 11, wherein the attachment element is arranged between the controllable light source and the camera.
14. The method according to claim 13, wherein the data stream is detected from the first image, according to which the controllable light source of the transmitter emits the modulated light.
15. The method according to claim 13, further comprising detecting an optical image from the second image.
16. The method according to claim 13, wherein the attachment element includes a plurality of alternating stripe-shaped lenticular regions and stripe-shaped planar regions.
